Figure 8

Schematic profile of the Nankai accretionary prism offshore the Kii Peninsula, southwest Japan. Orange dots indicate locations of fault gouges in which coal maturation and illitization were found by drilling into the shallow portions of the megasplay fault and the plate-boundary thrust. The tectonic setting of the duplex underplating of the tectonic mélange and basalt is shown on the profile. Tectonic settings of pseudotachylytes (red dots) and fluidized fault rocks (blue dots), which are identified in the Shimanto accretionary complex (the on-land analog of the Nankai accretionary prism), are shown in the profile.
